“…Four crosses L1 × T3, L2 × T2, L4 × T1 and L5 × T2 for traits weight of grains/spike and 1000 grains weight in addition two crosses L1 × T2 and L3 × T2 of weight of grains/spike showed significant positive (P≤0.05 or 0.01) Sij effects, they considered a good donor for these traits. These results are in line with those reported by Sarwar (2016), Ijaz & Kaukab (2017), Rajput (2018), Ranjitha et al (2018), Shah et al (2018a), El-Gammaal (2019), Alhossary (2020), Dhoot et al (2020), Gupta et al (2020), Kizilgeci (2020), El Nahas & Ali (2021 and Roy et al (2021b).

“…These results revealed that selection plants for these traits should be postponed to the later generations because of predominance of non-additive gene action for all studied traits. These consequences are in arrangement with those of Fellahi et al (2013), Abd El-Aty et al (2016), Ali (2019), El-Gammaal (2019, Dhoot et al (2020), Roy et al (2021b) and Chaudhary et al (2022).…”

The two lines, Sids 14 (L3) and Misr 2 (L5) were a good donner for biological yield/plant BY/P in g, no. spikes/plant NS/P and grain yield/plant GY/P in g. Significant positive general combining ability effects estimated for NS/P, GY/P, weight of grains per spike WG/S in g and 1000 grains weight 1000GW in g for line 4 (Misr 1) and line 5 (Misr 2). Sids 12 (T1) was a good donner for BY/P, NS/P, GY/P and 1000GW. Cross L4 × T2 showed significant negative (desirable) specific combining ability for days to heading. Four crosses, L2 × T3, L3 × T1, L3 × T2 and L4 × T1 exhibited significant positive specific combining ability effects for grain yield/plant. For days to heading, cross L3 × T2 showed significant negative heterosis relative to mid-parents and better parent. Six crosses, L3 × T1, L3 × T2, L4 × T1, L4 × T3, L5 × T1 and L5 × T3 showed significant positive heterosis for grain yield/plant over the mid-parents.

The present study was carried out in 9 diverse parents, their 36 hybrids and 2 checks evaluated during Rabi 2020-21 at Rajasthan College of Agriculture, Mpuat, Udaipur in RBD with three replications in three different environments in wheat for earliness and heat tolerant traits viz., days to 50 per cent flowering, leaf canopy temperature, total protein content in grains, heat injury, proline content and total chlorophyll content on pooled basis. The pooled analysis for above characters revealed that mean squares due to environments, genotypes, parents, crosses as well as parents v/s. crosses were significant indicating presence of overall heterosis for the traits. Out of thirty six crosses 5 crosses viz., GJW 463 x RAJ 4120, DBW 173 x RAJ 4120, GJW 463 x DBW 173, GW 451 x LOK 1 and DBW 173 x RAJ 3777 were found superior with maximum significant heterobeltiosis and economic heterosis for heat tolerant traits and earliness over the environments. These genotypes could be used to maintain transgressive segregants in future breeding programme.

The present investigation was undertaken to study the combining ability for yield and its components in F1 generation of wheat through Line × tester analysis. Experiment was conducted with 3 replications and 39 genotypes consisting 9 lines viz., HD 2851, HD 2893, HD 3226, PBW 677, HD 3086, PBW 725, Phule samadhan, Phule unnat, GW 273 and 3 testers viz., Faisalabad 2005, HW 2045, PBW 343 and their 27 crosses made in L × T mating fashion in randomized block design at experimental research farm, Lovely Professional University, Phagwara, Punjab during 2023-24. The genotypes (parents and crosses) exhibited highly significant variation for all traits studied indicating the presence of genotypic differences among these twelve genotypes under investigation. The mean square of parent vs crosses was found to be highly significant for all traits studied expect 1000 grain weight. Further partitioning of crosses mean squares i.e., Line × tester analysis showed highly significant for all traits studied. Line × tester analysis is used in predicting the effects of the general combining ability of parents and specific ability combining of their crosses The lines PBW 725, GW 273 and tester PBW 343 exhibited significant GCA for grain yield. The lines PBW 725, HD 2893 and Phule unnat which performed good combining ability effects for biological yield per plant were also good combiners. Among the cross combination PBW 725 × PBW 343 showed significant positive SCA for grain yield and biological yield per plant, whereas, PBW 725 × Faisalabad 2005, HD 2893 × HW 2045 and GW 273 × PBW 343 was a good specific combiner for 1000 grain weight.
